DuMPlNc-'CAR SPECIFICATION forming part of Letters Patent No. 622,382,- aatea April 4, 189e.

Application filed December 28, 1898.- Serial No. 700,531. (No model.)

To a/ZZ whom it may concern:

Be it known that I, MIOHAELJ. MCKINNON, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented new and useful Improvements invDuInping-Cars, of which the following is a specification.

My invention relates to that class of dumping-cars which embrace bodies susceptible of being canted longitudinally -in one direction and laterally in opposite directions; and it consists in the peculiar and advantageous construction, certain novel combinations,and the adaptation of parts hereinafter described, and particularly pointed out in the claims appended. i

In the accompanying drawings, Figure 1 is a transverse section of my improved car,taken in the plane indicated by broken line l l of Fig. 2. Fig. 2 is a longitudinal central section taken in the plane indicated by broken line 2 2 of Fig. l. Fig. 3 is .an enlarged detail transverse'section taken in the plane in-` dicated by broken line 3 3 of Fig, 2.

In the said drawings similar letters designate corresponding parts in all of the views, referring to which- A A are axles carrying wheels B and journaled at their ends in boxes C, and D are longitudinal stringers connected to and supported by the boxes. On these stringers are mounted and suitably secured a transverselydisposed pedestal E and a similarly-disposed pillowblock F, the former being arranged between the axles and the latter adjacent to one end of the car, as best shown in Fig. 2.

The pedestal E has its upper edge inclined in opposite directions, as indicated by a, and in the preferred embodiment of the invention it is provided in its rear side with a curvilinear recess b and is also provided with a longitudinal central aperture c, which interects the recess after the manner shown in G is a ball mounted and secured upon the upper end of the pedestal, and H is the carbody, which is provided at the center of its under side with a socket I, receiving the ball a horizontal direction incident to its longitu dinal inclination, the circular bar .I is pro= vided. This bar .I is. arranged to move through suitable guides d, located in the re cess b of the pedestal, and is connected at its ends in a hinged manner to the under side of' the body H by pintles e, which are dis' posed transversely with respect to the body for a purpose presently described. These pintles e are also arranged in the same transverse and horizontal planes as the ball-and'- socketbeari ng between the pedestal and body, and hence it will be seen that they will in no manner interfere with the longitudinal or endwise inclination of the body. Vhile this is so, the bar J, being held against horizontal movement by its guides, will effectually pre vent the body from swinging or swaying horizontally incident to its longitudinal or endwise inclination. When canted longitudi= nally, the forward portion ofthe body is de'- signed to rest on the forward ends of the stringers D, which are preferably beveled, as indicated by f, and when said body is in its normal position its rear end is supported by the pillow-block F and is detachably secured to said block through the medium of a pivoted link g and a keeper h, which latter is designed to be turned when it is desired to release the rear end of the body to permit of the-same being canted longitudinally.

In order to permit of the body H being inclined laterally in either direction without thenece'ssity of disconnecting the end of the 4same from the pillow-block F, I provide on said block a pillow K, havinga concavityt'in its upper side, and equip the lbody with a head L of circular form in cross-section, as'

socket bearing between the body and pedestal E. From this it follows that when the body ICO j and the aperture c of the pedestal, and isV designed to take Ithrough an aperture 7c in the strap J, as shown. To the bolt M is connected a hand-rod N, which extends through a guideaperture in the pillow-blockF to the rear end of the car, so as to permit a person standing at such end of the car to release the strap .I when it is desired to tilt the body laterally.

Vhen the body is returned to its normal horizontal position subsequent to being tilted laterally in either direction, the springpressed bolt M will enter the opening 7c in the strap J as soon as they coincide or register, and thereby automatically secure the body in such position.

In order that the contents of the body may be discharged from the forward end or either side thereof, said body is provided with an end gate P and side gates Q. These gates are pivotally connected to or hung from standards R, rising from the corners of the body, and are normally held against swinging outwardly by keepers S S. These keepers are in the form of rock-shafts, and they are journaled in suitable bearings in the body and are-provided at one end with an angulartoe fm, designed to assume a position at the outside of a gate and prevent the same from swinging outwardly, and at their opposite end with a crank-handle n. The keeper S of the end gate P is disposed longitudinally of the body and has its toe m at the forward end and its crank n at the rear end thereof to enable an attendant to conveniently release the gate P after he has disconnected the rear end of the body from the pillow-block F. The keepers S' are disposed transversely of the body, the crank of one being arranged at the same side of the body as the toe of the other, as shown.

By reason of the construction described it will be noticed that the body H may be tilted longitudinally and dumped by simply disconnecting its rear end from the pillow-block and slightly raising said end and turning the keeper S to disengage the toemthereof from the gate P. All this may be done by a person standing at the rear end of the car with but a minimum amount of elTort, rand when the body is tilted it will be held against swinging or swaying horizontally by the fixed strap J. The body II may also be tilted laterally in either direction by a person standing at the rear end of the car, it being simply necessary for such person to disengage the b'olt M from the circular guide J through the medium of the rod N and then pull the desired side of the car downwardly. IVith this done the person mentioned or a second person has but to turn the proper keeper S' to release the side gate of the body, when said body will be discharged of its contents.

Vhen desirable, the transverse rock-shafts S may be omitted, and in lieu of the same a gate-latch may be employed at each side of the body, the said latches being arranged to contact with the stringcrs when the car is dumped, and thereby release the gates and enable the body to discharge its contents. These latches are common in the art to which my invention appertains, and I have therefore not deemed it necessary to illustrate the same.

The body is held against swinging or swaying horizontally incident to its lateral inclination by the head L bearing on pillow K, and when it is returned to its horizontal position it is automatically secured in such posi tion by the bolt M engaging the arc-shaped or circular guide J. Y

When tilted longitudinally, the body Il is stopped by and rests on the ends of the stringers, and when tilted laterally it is stopped by and rests on the inclined edges a of the pedestal.

The main frame of the car is preferably made up of the stringers, pedestal, vand pillow-block described; but it may be of any other construction suitable to the purposes of my invention. It is also obvious that the said frame may in practice be provided with the various appurtenances common to railway-cars.

Having thus described my invention, what I claim is- 1. In a dumping-car, the combination of a main frame, a body, a ball-and-socket bearing interposed between the center of the body and the frame, a transverse rocker-bearing interposed between the body and frame adjacent to one end and arranged in the same horizontal and longitudinal vertical planes as the ball-and-socket bearing, acircular or arcshaped guide-bar connected at its ends to the body in a hinged manner, .and movable in guides in the frame, and suitable means for detachably securing the body against longitudinal inclination, and also against lateral inclination, substantiallyas specified.

2. In a dumping-car, the combination of a main frame comprising a transve1sely-dis posed pedestal having its upper edge inclined in opposite directions, and a transverselydisposed pillow-block, a ball mounted and secured on the pedestal, a pillow mounted and secured on the pillow-block and having a concavity in its upper side, the body having the central socket receiving the ball, and the longitudinally-disposed head of circular form in cross-section, a detachable connection between the end of the body and the frame, a circular or arc-shaped guide-bar connected at its ends in a hinged manner to the body and movable in guides on the pedestal, and suitable means for detachably securing said bar against casual movement, substantially Vas specified.

3. In a dumping-car, the combination of a main frame comprising stringers having beveled ends, a transversely-disposed pedestal having its upper edge inclined in opposite directions, and a transversely-disposed pillow-block, a ball mounted and secured on the pedestal, a pillow mounted and secured on IOO IIO

aperture in the' guide-bar, anda rod connected to said bolt and extending through a guide in the pillow-block, substantially as specified.

In testimony whereof I have hereunto set 15', my hand in presence of two subscribing WitnesseS.
